In a New Keynesian DSGE model with non-Ricardian consumers, we show that automatic stabilization according to a countercyclical spending rule following the idea of the debt brake is well suited both to steer the economy and in terms of welfare. In particular, the adjustment account set up to...

In a New Keynesian DSGE model with labor market frictions and liquidityconstrained consumers aggregate unemployment is likely to increase due to a non-persistent government spending shock. Furthermore, the group of asset-holding households reacts very differently from the group of...

We present the estimated large-scale three-region DSGE model GEAR picturing Germany, the Euro Area and the Rest of the world. Compared to existing models of this type, GEAR incorporates a comprehensive fiscal block, involuntary unemployment and a complex international structure. We use the model...

In this paper, we assess the impact of major German structural reforms from 1999 to 2008 on key macroeconomic variables. By many, these reforms, especially the Hartz reforms on the labor market, are considered to be the root of observed imbalances in the Euro Area. Our simulations within a...

In this paper,we assess the impact ofmajor German structural reforms from1999 to 2008 on key macroeconomic variables within a two-country monetary union DSGE model. Bymany, these reforms, especially the Hartz reforms on the labormarket, are considered to be the root of thereafter observed...

This paper develops a medium-scale dynamic, stochastic, general equilibrium (DSGE) model for fiscal policy simulations. Relative to existingmodels of this type, our model incorporates a two-country monetary union structure, which makes it well suited to simulate fiscal measures by relatively...

We quantify the effects of population aging on the U.S. healthcare system. Our analysis is based on a stochastic general equilibrium overlapping generations model of endogenous health accumulation calibrated to match pre-2010 U.S. data. We find that population aging not only leads to large...

We quantify marginal excess burden, defined as the change in deadweight loss for an additional dollar of tax revenue, for different taxes. We use a dynamic general equilibrium, overlapping generations model featured with heterogeneous agents and a realistic structure of corporate finance and...

In this paper we quantitatively explore the overall welfare bene ts of social health insur-ance which is embedded in the US mixed health insurance system. We compare the currentUS mixed insurance system to three alternative systems: (i) a no health insurance system,(ii) a purely private health...

We simulate the fiscal stimulus packages set up by the German government to allevi-ate the costs of the COVID-19 pandemic in a dynamic New Keynesian multi-sectorgeneral equilibrium model. We find that, cumulated over 2020-2022, output lossesrelative to steady state can be reduced by more than 4...
